Dan,
	I've been following this with great interest. This may not be the sort
of input you're looking for, but here goes...
	Have you thought about trying to measure the pitch or the tension
change (if any) in the duplex area and between the tuning pins and capo
or agraffes? It seems pretty important in order to establish a complete
idea of what is happening. Checking the duplex area aurally would be
possible but maybe not accurate enough.?
